This part PCM part # belongs to a 1996 Bonneville, yet in the list of applications, it says it can work from 1987 to 2002. Sorry about the copy and paste here, but it kinda shows you the applications for this PCM. Just curious about upgrading current OBDI to OBDII.

What say ye?

You cannot upgrade without also changing all your sensors, adding a MAP sensor, swapping the entire wiring harness out (requiring a PCM relocate for you), and alot of other stuff.

The BOX may be interchangeable, but the Eprom is not without alot of work. This is no simple task even with the 92 and 93, which you would think would be nearly identical.

So, in theory, this would be possible? PCM, wiring harness, all sensors on the engine. So, only difference in the sensors would be values correct? They are mechanicaly swappable?

Should this happen, walk into local Autozone and buy a part.
Well, sir, what kind of car is it?
Um, its a 95 and a 96!

It'* possible in the same sense that I can swap in a 1996 Plymouth Neon PCM and wiring harness/sensors into my 93 SSEi.

Worth the trouble and headaches? I don't think so.

I understand they are far different, hence the reason I am looking into this. Yet, what more difference could it be? Engines are the same, are they not? I could see the sensors having different values. If I am just beating a dead horse, shoot me instead. Maybe I need to compare the 2 SM'* for the 2 different years.

As I always say, When their is a way, their is a will and vice versa.

Engines are the same in a way, yet there are differences. Both being L36'* isn't really the whole story.

96 is managed in a totally different way, including with a MAP sensor that your 95 doesn't have. In addition to that, I believe the crank pulley is different, which means the engine/PCM management for fuel and spark timing pulses is different. You also (IIRC) have only one O2 sensor, which is a different part number than the 96'* front O2, and the 96 also has a rear O2 to be OBD2 compliant. There may be other differences.

The crank pullies are the same. I have a GP harmonic balancer.
Why would you want to upgrade anyways?

Poops and giggles I guess. Want to monitor parameters etc. I have this OBDI adaptor that I can hook up to PC and monitor some values, but not like with that one adaptor you can mount in your dash. Also want to confuse the inspection guys every year. Here in NY, they scan your car for codes when getting inspected. 96 and newer anyway. 95 they just do a safety inspection. I DONT KNOW! Just want to do something different than everyone else. I WANNA BE LIKE MIKE!
